RouteDestination contains a ViewSet object. takes a RouteHandlerCallback containing a RouteDestination. RouteHandler.update() takes a RouteHandlerCallback containing a RouteDestination.

viewsetA ViewSet objectRequiredA ViewSet object that specifies the view to display.

The view to display. Supply a ViewSet object to a RouteDestination.

viewNameStringRequiredThe viewName key maps to the viewName property for the outlet. It accepts either:
  • a Promise to a route handler module: { default: import('my/routeHandler') }.
  • a ViewInfo object

In LWR, modules are always provided via a Promise object. Promises allow the module code to be lazily loaded, improving application performance.

If a single page reference maps to more than one view, you can specify more than one outlet where each outputs a different view component. For example: { default: import('my/routeHandler'), sidebar: import('my/sideHandler'), footer: import('my/footerHandler') }. Check out Outlets for more information about using multiple outlets.

An object containing a Promise to a route handler module and a string specifier for the module. Supply a ViewInfo object to a ViewSet object.

modulePromiseRequiredA promise to a route handler module.
stringStringRequiredA string specifier for the module, like my/recipePage. Simple or straightforward use cases typically don't require a specifier. In other cases, the specifier for the module can't be determined from a Promise alone, so you should manually define the module's string specifier for the route handler.
